The Ruko-815042 twist drill bit is a high-precision tool designed to meet the demands of drilling high-strength materials. Made of high-speed steel (HSS-G), this drill bit features a brazed carbide cutting insert, ensuring exceptional durability and performance. Its helical design allows for efficient chip evacuation, optimizing the drilling process and reducing the risk of overheating.
The fine-grained K20 material used in its manufacture makes it suitable for universal use, and particularly effective in high-strength steels.
It is important to note that for drilling in these materials, the use of continuous cooling is recommended, which ensures optimal performance and extends the tool's lifespan.
